  • Bacterial Biofilms Found to Quickly Clog Medical Devices

    Molecular biologists and engineers at Princeton University in New Jersey discovered that bacterial formations called biofilms can quickly tangle and trap other bacteria, disabling medical devices. The study by postdoctoral researcher Knut Drescher and colleagues appears online in a recent issue of Proceedings of the National Academy of Sciences (paid subscription required). Drescher, working in…

  • Gold Nanoparticle Biosensor Developed for Simple Diagnostics

    Biomedical engineers at University of Toronto in Canada developed a simple, portable DNA diagnostic process using gold nanoparticles and requiring only small specimen samples. The team of doctoral candidate Kyryl Zagorovsky and professor Warren Chan reported their findings online in a recent issue of the journal Angewandte Chemie (paid subscription required). Zagorovsky and Chan (pictured…
